Understanding Tinkercad and Wheels
Tinkercad is a popular online 3D design tool that is accessible to beginners and allows for the creation of various models, including wheels. Creating a wheel in Tinkercad involves utilizing basic shapes and modifying them to meet your design specifications. This guide will walk you through the step-by-step process of making a simple wheel in Tinkercad.
Accessing Tinkercad
To start designing a wheel, first, head to the Tinkercad website. If you do not have an account, you will need to sign up. Create a free account or log in if you already have one. Once logged in, click on "Create New Design" to open a blank workspace where you can start modeling your wheel.
Creating the Base of the Wheel
Select the Cylinder Shape: From the right-hand side of the screen, you will find a variety of shapes. Locate the "Cylinder" and drag it onto the workplane. This will serve as the main body of your wheel.
Adjusting the Dimensions: Click on the cylinder to select it. Use the white squares (handles) around the cylinder to adjust its size. For a standard wheel, consider setting the diameter around 20 mm, depending on your project needs. The height should be adjusted to about 5-10 mm.
- Changing the Color: To differentiate your wheel from the rest of the model, you may want to change its color. With the cylinder selected, look for the color control in the shape’s properties panel. Choose a suitable color for your wheel.
Creating the Wheel’s Hub
Add a Smaller Cylinder: To create the hub (the center part of the wheel), drag another cylinder onto the workplane.
Resize the Hub: Select the smaller cylinder and adjust its dimensions. A good size for the hub could be around 10 mm in diameter and 5 mm in height. Make sure to position it in the center of the larger cylinder.
- Align the Hub and Wheel: To ensure that the hub is perfectly centered in the wheel, use the alignment tool. Select both the hub and the wheel, then click on the alignment icon in the top-right corner of the interface, and align both shapes centrally.
Making the Wheel Functional
Group the Shapes: Once you have your wheel and hub aligned, you need to combine them into a single shape. Select both the hub and the wheel. Using the "Group" option in the top toolbar (which looks like a square overlapping a circle), you can merge them into one cohesive unit.
- Export Options: After grouping, preview your wheel. If it looks good, you can prepare to export it for 3D printing. Click on the “Export” button located in the upper right corner, choose the appropriate file format (such as STL), and download it.
Optional Modifications
For added functionality or stylistic flair, consider the following:
Adding Treads: Sculpt additional features on the outer edges of the wheel for tread patterns. Using the “Box” shape, create ridges or grooves and align them with your wheel’s perimeter.
- Hollowing Out the Wheel: If you wish to create a hollow effect, group your shapes appropriately and use the "Hole" feature to subtract material, providing a more lightweight design.
FAQ
1. Can I create wheels of different sizes?
Yes, you can create wheels of any size by simply adjusting the dimensions of the cylinders. Make sure to scale the hub and wheel proportionately.
2. Can I make a multi-part wheel assembly?
Absolutely! You can create multiple components of a wheel assembly, such as spokes or axle mounts, and then group them together to form a complete wheel design.
3. Is it possible to print the wheel with moving parts?
Yes, Tinkercad has features that allow you to create designs that print in place, including wheels that can rotate. Make sure to design with clearances that support movement for the best results when 3D printing.
